.//'o all whom it may concern.'

Be it known that I, SIMEoN SoHooN JACKv Readville, in the county of Norfolk, State ofl Massachusetts, vhave inventedV a certain new and useful Improvement in Differential Filling-Supply-Gaging Devices for Looms, of Which the following is a specification, reference being had Atherein tothe accompanying drawings.Y

The invention has relation to devices for indicating when the filling-supply Within the .shuttle at Work upon the lay of a' loom to ..a .predetermined amount short 'of complete exhaustion.v

I- employ, as heretoforeihas. been proposed-in some instances'tvvo independentlymovable-contactfrnembersarranged to act each 4'time the Working shuttle occupies the shuttle-box of the lay,- one the Wound yarnmass Withinfthe said shuttle, and the other having i'tspofsition' given .toit from a 0f 'the yamrelative positions" offthe each time they are brought mass itself- The contact-members,

A into action, are fixed` by. the relationbetween the exterior of 30,

the base of the yarn-mass and the datuinsurface This relation continues4 unchanged until the yafrirA commences toweave off from the said'base. As soon as .it begins to vary as a result of,decrease in other When next called the diameter of the saidbase, a variation results in the positions members are given with relation to each vinto action, Which -variation proccedsas the yarn continues 'to rontrolled by 'ply of Weft or vmined extent In accordance with the in veninv connection .With

weave ofi'. tion, I employ a detent one of the said nection Withthe other of thelatteria latch which is governed by engagement with the' said detent; and in connection With thelatch I provide a controller', operatively engaging therewith and hold in 'normal tion thereby, and released for action as a result of the release of the latch. The .parts are so related' that the Vlatch I.normallyis the detent, but When the su filling remaining Withint e .shuttle has been reduced to thepredetervthe positions which are then assumed by latchto be- Speccation of Letters Patent.

The said controller is operatively combined With other parts in the loom to bring about the required result in the Working thereof, which result `may be a stoppage of the loom, or a refproviaion for adjustment to p lenishnient of the filling-supply.` Icom-l bme vWith the controller means for automatically resetting the same'and the latch.

An embodiment of the invention is shown in the drawings, in which latter,

Fig. 2%is a plan View of one of the contact-members and the detent connected therewith. an end-.elevation of the parts which are shown in Figs. l and 2.

At 2l is an arm fixed upon the said rookshaft, with opposite projections, one of which extends across in frontof the arm 19. The roclrshaft 20 is mounted in a pipe-bearing 22 (Fig. l) on a stand 23 attached to the end-frame 1, and is'provided at its o uter end with a knocking-off piece 24 `(Fig. adapted to engage'with a projection 25pof the shipper-handle 26, the latter being iixed upon the supporting-shaft 27, which is mounted in bearings upon the loonrframe. When failure of weft permits the weft-hain- -nier toengage the weft-fork andv move the Weft-forlr slide forward, the forward turnl ing movement of the arm 1.() thereby occasioned causes such arm, by its engagement with the corresponding projection of arm 21, to move forward the arm also, th .reby turn'ingthe knocking-off roclshaft so as vby its piece I24 to' move the shi pgu i"liandle 26 to unship the driving-power.

At 28 is. a shuttle, shown occupying thev shuttle-box in Figs. l, 2 and 3, and separately in Figs. 5 and 6, and at 29 is a bobbin in place within the body of such shuttle, such bobbin containing a Vsupply of weft-yam` or' illing, whichis represented as having been partially woven off, 29a beingthe head of the said bobbin, and 29b metal rings 'upon the said head. As thus far mentioned, the parts themselves form no portion of the invention.

Referring, now, to the devices in which the' invention resides, and the parts Amore immediately associated 4t-herewith,-at 30,- 31-, (see, more particularly, Fig. 2) are the contactsmem thereof are arranged properlyto enable the member 30 to be 'governedby or through the base-portion of thewound mass of weft yarn or filling within 'the shuttle, andthe member 31 b or through-the datum-surface aforesaid. n thefforrn of the inventionl that is here shown the contact-member 30 is controlled indirectly bythe said ybase-'por-I tion through a fe'eler 32 (Figs. 5 and '6) which is movably mounted on `the shuttle,

and with which the contaet-1ne1nber engeges,

the said feeler, inlttsslturn, `being arranged to'l press against .the'surface of the 'said baseportion of ,the yarn-mass. InFigs. 2, 5 and 6 the feeler consists of a strip of elastic inaterial, as steel, secured by one endl to the shuttle-body, the acting portion of such strip extending lengthwise of the shuttle within the latter, toward 4the end of the shuttlecavity .at which the bobbin-head is located. A longitudinal slot 33 formed in the front wall of the shuttle-body permits the acting portion of the contact-member to engage the feeler. ln this form of the invention, also, the datum-sindaco iss-constituted by ,the front'surface of a movable pic-co, 34, work ers. The acting portions v ing in the slot 33 and adapted to engage with the periphery of the bobbin-head 29a, or with .the peripheries of the rings 29b upon the bobbin-head.' The said piece 34 has an elastio' extension by which it is attached to theV bracket 37 projecting outward from the end f of the loom. The slides are movable in the said guideways forward and backward in the tloom. They are kept in the guideways by means of gibs 38, 38, (see, more particularly, Fig.. 2) that are 4secured in place upon the support 35 by screws 39, 39, entering the said support, the construction enabling the slides conveniently to be 'removed and re-v placed. The acting portions of the contactniembers are at the rear endsof the latter and they are so located that when the lay 4beats up the feeler and the movable piece 34 carried by .the shuttle will act against the said acting portions soas to move the slides forward in the guidewaysy.' The slides are backed up by springs 40, 40, shown as exl 4panding spiral springs surrounding cylindrical pins 4l, 4l, project-ing forwardly from the sl ndpassing through guideeyes in a for port. n The sar. i rings are compressed be`- tween the guida-reyes and shoulders which are provided upon the slides at 43, 43,- and they act vwith'a tendency to 'press the slides rearward, and tokeep them in their normal positions, vwhich zlatter. are determined through. the engagement of stop-'collars'v 44,

44, carried bythe pinsBG', 36, with the front d extension 42 of the supiin surface of the said .extension 42.. *The said normal position-may be adj usted by shifting the-positions of thelstopvcollars ,upon the said pins. Topermit this adjustment, the

`stop-,(1,4ollars are-secured in place by means l" ofthe clamp1ng-screws45, '45. The contact-` .n'iernbersl may be adjusted .independently of sired position' of-adjustment by means lof screws 46,14,worlring 'through slots inl the horizontalportipn ofthe stand 36,.Figs. 1

detent is shown at ett) (Figs. 2 and 2a) and a latch at 50. The said detent is mounted upon the contact-member and is mov able therewith. It consists of a block Which is secured in place upon the said contactmember h v a screw 51 and washer 52, the stem of the said screw passing through a slot 53 in the said block that is elongated in the direction 'from il'ront to rear. The said slot provides for :uljustment of the detent upon the contact-member il() in such direction. ihe latch is pivotally mounted at 54 (Fig. t) upon the contact-member o1, and rests upon the detent'. lt is formedwith a slot 55 (Figs. 2 and 3) elongated in the dirertion trom trout to rear. 4 l

The controller hereinfshown is constructed with a horizontal supporting-shaft. 5G extending transrerseljT ot the loom and mountv4 ed in beat-inge 5T. 5T, upon the stand 3G, and with an arm 5S sleeved upon the said snpporting-shalt and fixed thereon with cupac ity tor a ng'ular adjustment around the saine by m anis ot. a clan'ipii'ig-screw 59. The said arm carries a pin ttt) which works in the slot` .'75 of the latch. Through the engagement ot the said pin in the said slot the latch and controller are operatively connected so that when the latch is raised it nplifts the arm 5S. turuincr the controller, and so long; as the latch is held up by the detent the arm is held uplitted and the controller is kept locked in the. position which was given to it. The elongation ot the slot 55 permits the latch to reciprocate Iforward and rearward With the rontact-member with which it is connected, without interfering with the inter-engagement ot' the latch and controller.

l-ach time the lawy beats up the contactuu :obers are both pushed t'orward in unison. und as the la;y recede` they are caused to follow bach to their normal positions by the action oll their springs itt), it). During' these m ..-\'ements they talfe the detent aud latch restingY with them. and the latch remains upon the dctent. and the controller locked. so lou; as there is a sullicient amount ot' raro or lilling in the laiswportion ot' the Varnmass within the shuttle to act to lceep the detrnt in enna, fcmen t with the latch. ili'hen \'a|^n begins to wearepll' from the base et' the y.'ai'irni eo that the diameter there.- i tiroirs sin the forward movement given it.- tbf ront:act-member ltl and the detiti land the. other with the, upper end ot' tent is less than with the base of its t'ull diameter, while that of contact-member 3l and the latch remain the same in extent as before. The diti'erenee in the distances which the detent and latch. respectively, are carried forward by the Abeat-np of the lay will increase lnfogi'essively asthe base-portion of the Yarn-mass lessens in diameter,

until finally. when the amountof yarn vre-v mailling' within the shuttle has been reduced to the limit deemed advisable.` the detent will remain behind to a sutlicient extent to permit the latch to pates Vtorward 0H the Ylront end ot the detent. latch will be releasedtrom restraint and the controller will be permitted to turn, bringing' about the change in the working ot the loom for which provision has been made in the construction ot the latter. lly adjustment of the detent torwad or back upon the contact-member lt), so as to alter the position of the detentI relati\'e'to the latch. the 4stage in the nnwinding of the wet'tsyarn or fillingl at which the release ot the latch takes place -niawy be regulated, so that such release may take place earlier or later. This enables me to set the parts to act with close exactness when an)v desired amount ot Yarn or tillinn' still remains within the shuttle.

The devices through which the controller acts to bring' about the desired change in the working' ot the loom may Vary according' to circumstances. llerein, the controller rock shat't :lo has fixed upon its inner end an arm til carrying' a pin (3? on which rests a dog (3J-). The latter orerhang's by its rear end the path ot'the head ot' the `goose-neck or wett-hammer lli. and is pivotalliV connected at its forward end to anarm (34 which is sleeved upon the knockingolt' rot-,kshatt 2() and capable ot' turning upon the. latter.y The dog is acted upon b v-a contracting spiral spring' (35 having om` end thereof engaged with the dog' arm tit. as vshown in ltigr. 4. The said spring' tends to depress the dog, and acts through the pressure of the dog' upon the pin (12 with a tendencv to turn the controller. rlhis tendency is epposed through the engagement ot t he controller with the latch. and ol5 the latch withlthe detent. lVhen the latch is'lreed i'ron't the restraint ot the fle-tent in consequence ot exhaustion otl the supply ot' wett or filling' in the shuttle to the pret'letermined extent. the controller turns. permitting the don' to swine' so as to curr)Y its rear end into the path of a shoulder (iti (Filez Ll) on the `goose-neel; or wett-hammer. Then, as the latter goes forward, the said shoulder en-l Afringes the dogand pushes it toi-ward, swing# me' the arm tikt in the same direction so that 1t acts against one otl the transverse projec tions ot a rm 2l upon the knocking-ott' roch'- 'llherenpoln the shaft 20. Thereby thev said rockshaft is turned sol as by its projection: to operate lhc shipper-handle 26.

.For the purpose of automatically resetting the devices for continued operation, I provide means .for automatically raising the latch and replacing it in engagement with the top of the detent. To this end I furnish the rear end of dog 63 with a hook 67. As thc gooseneck or weft-hammer pushes the dog forward in the manner just stated, the dog slides upon the pin 62 until such hook engages with the pin. By such engagement the arm 6l andcontroller are turned by the remainder of the advancing movementof the dog with the gooseneclr or weft-hammer.

By the turning movement of the controller thus occasioned the latch is raised fromin front of the detent, whereupon the contactmember 3l Will' be forced rearward by its spring 40 until arrested b engagement of its stop-collar 44 with its guide-eye at 42. This movement of the contact-member .3l Will carry the latch on top of the detent, thus replacing it in normal engagement with the detent again, in readiness for the continued working of the parts as before. In addition, the upwardly-extending curved path taken by the pin 62 as'arm 6l and the'controller are swung in the manner described will raise the rear end (.f the dog 63 so as to disengage it from the shoulder 66 of the gooseneck or weft-hammer and keep it out of the path of' such shoulder. Thereafter, when the arm 64 and dog 63 are caused to move rearward into their normal position, they said end of the dog will be held clear of the shoulder.
